Audrey Watters, like other critics before her, takes MOOCs to task for their high drop-out rate. But let's keep this firmly in perspective. If people quit work, moved to a new city, invested thousands of dollars to pay tuition, bought books and then attended a class, then yes, I would be concerned about high rates of drop-outs. But if a person fills in a form, reads a few posts, and perhaps offers up a comment, then the drop-out rate isn't anything like the same sort of problem.
